From 1988 to 1993, a special high performance XJR-S version equipped with the {{convert|5344|cc|L|1|order=flip}} [[Jaguar V12 engine#5.3-litre HE|HE V12 engine]] was produced by the newly formed JaguarSport, a separate company owned in a ratio of 50:50 by Jaguar and [[Tom Walkinshaw Racing|TWR Group Limited]] specialising in developing high performance Jaguar sports cars. The car had a distinctive [[body kit]], special 15" alloy wheels, 235/60R15 Pirelli P600 tyres, a unique suspension system utilising modified coil springs and Bilstein shocks, a luxurious interior with Connolly Autolux leather along with walnut wood trim, and handling improvements. The first 100 of these cars were named "Celebration Le Mans" to commemorate Jaguar's [[1988 24 Hours of Le Mans|1988 win]] at the [[24 Hours of Le Mans]] and were only sold in the UK. Between 1988 and 1989, a total of 326 XJR-S cars were produced with the {{convert|5344|cc|L|1|order=flip}} engine which has a power output of {{cvt|318|hp|kW|0}}. After September 1989, the displacement of the engine was increased to {{convert|5993|cc|L|1|abbr=on}} and it was now equipped with [[Zytek]] fuel injection and engine management system. This was different from the standard [[Jaguar V12 engine#6.0 Litre HE|6.0-litre engine]] used in the late XJS models and was unique to this model. The power output was raised to {{cvt|333|PS|hp kW|0}} at 5,250 rpm and {{convert|495|Nm|lbft|0|abbr=on}} of torque at 3,650 rpm due to a higher compression ratio of 11.0:1, a new forged steel crankshaft, increased bore and forged alloy pistons. A modified air intake system and a low loss dual exhaust system was also standard on the model. The engine was mated to the 3-speed GM400 automatic transmission utilising a recalibrated valve body and had faster shift times. The car was equipped with 16" Dunlop D40 M2 tyres for better grip. These modifications resulted in a top speed of {{convert|160|mph|kph|abbr=on|order=flip}}. During a comparison test conducted by Motorsport magazine in 1997, the XJR-S outperformed the other competitors which included a [[BMW 8 Series (E31)|BMW 850i]], [[Porsche 928|Porsche 928 GT]] and a [[Ferrari Mondial]].<ref>{{cite web|url=https://www.hemmings.com/blog/article/1993-jaguar-xjr-s/|title=1993 Jaguar XJR-S|date=July 2009|first=Craig|last=Fitzgerald|publisher=Hemmings|access-date=2019-04-11}}</ref><ref>{{cite web|url=https://www.motorsportmagazine.com/archive/article/december-1997/96/jaguar-xjrs|title=Jaguar XJRS|date=December 1997|first=Andrew|last=Frankel|publisher=Motorsport Magazine|access-date=2019-04-11}}</ref>

A total of 787 [[coupé]]s and 50 convertible cars were built for the world market. In the United States, to commemorate the [[Jaguar XJ220|XJ220]] launch in 1992, a limited number of 100 XJR-S coupés and convertibles were produced. Based on the facelift model, these were for the American market only. These included 22 Signal Red coupés, 22 Signal Red convertibles,<ref>{{cite web|url=https://www.thetruthaboutcars.com/2018/01/rare-rides-1993-jaguar-xjs-actually-xjr-s/|title=Rare Rides: The 1993 Jaguar XJS, Which Is Actually an XJR...S|date=2018-02-01|first=Corey|last=Lewis|publisher=The Truth About Cars|access-date=2019-04-11}}</ref> 22 Jet Black coupés, 27 Jet Black convertibles, 2 Flamenco Red coupés, and the Silver Frost 'Press Cars' of 4 coupés and 1 convertible.{{citation needed|date=April 2019}}
